C#实现读取匿名对象属性值的方法示例总结

var objUser = new {Name="Lilei",Age=18 };
//此时可直接读取匿名类属性
Console.WriteLine("Name:" + objUser.Name);// Name:Lilei

static object GetObj()
{
 var obj = new { Name = "Lilei", Age = 18 };
 return obj;
}
static void Main(string[] args)
{
 var obj = GetObj();//此时已无法通过obj.Name的方式获取属性值了
}

static object GetObj()
{
 var obj = new { Name = "Lilei", Age = 18 };
 return obj;
}
static void Main(string[] args)
{
 var obj = GetObj();
 //此时可通过反射的方式获取属性值
 string objName = obj.GetType().GetProperty("Name").GetValue(obj).ToString();
 Console.WriteLine(objName);// Lilei
}

class Program
{
 static void Main(string[] args)
 {
  var obj = GetObj();
  var user = obj.ObjCast(new { Name = "", Age = 0 });
  Console.WriteLine("Name:{0},Age:{1}", user.Name, user.Age);// Name:Lilei,Age:18

  var objList = GetObjList();
  var userList = objList.Select(p => p.ObjCast(new { Name = "", Age = 0 })).ToList();
  userList.ForEach(p =>
  {
   Console.WriteLine("Name:{0},Age:{1}", p.Name, p.Age);
  });
  // Name:Lilei,Age:18
  // Name:HanMeimei,Age:20
 }
 static object GetObj()
 {
  var obj = new { Name = "Lilei", Age = 18 };
  return obj;
 }
 static List<object> GetObjList()
 {
  List<object> objList = new List<object>();
  objList.Add(new { Name = "Lilei", Age = 18 });
  objList.Add(new { Name = "HanMeimei", Age = 20 });
  return objList;
 }
}
static class Extensions
{
 public static T ObjCast<T>(this object obj, T sample)
 {
  return (T)obj;
 }
